Businesses that want to benefit from the many advantages of Session Initiation Protocol (SIP) trunking have an initial challenge to overcome: finding the right provider. With the sharp recent rise in Voice over IP (VoIP) telephone services, the market has seen a veritable explosion in the number of agents and service providers offering SIP trunking capabilities. Businesses need to proceed with caution during the selection process.

One important thing to keep in mind is that price isn’t the only factor to consider. It’s far more pressing to find a solution that’s right for the business, as this is where the real value will come from.

To that end, following are nine considerations that will help enterprises find the right SIP trunking partners.


Customers of cut-rate providers are at increased risk for losing service, which is a position no business can afford to be in for long. Ask the vendor about the infrastructure they have in place to restore service in the event of an outage, keeping in mind that multiple service locations, backed-up Internet connectivity, and hardware redundancies all improve reliability.

Uptime Guarantees in SLAs

Getting the terms of the deal in writing through a service level agreement (SLA) is good protection. One must-have in an SLA is a pledge that uptime is guaranteed 99.999% of the time. Reliable providers will always make this offering.

Add-on Features

A red flag for potential problems is the presence of redundancy features in the list of service add-ons. These should be standard. If they’re not, it’s a sign that the service provider is more concerned about up-selling than providing reliable service.

Customer Support

It’s normal to go through some growing pains when switching to a new SIP trunking system, so choose a vendor that offers these key customer service guarantees:

  • 24/7/365 and multi-channel availability
  • Online-deliverable troubleshooting capabilities
  • Redundancy features
  • Knowledgeable staff


Avoid service providers that penalize customers for altering the service agreement. Scalability should be built in.

UC Options

Choose a service provider that offers the option to upgrade the system to include unified communications (UC) features. This gives the customer added flexibility and scalability options.

Security Features

Key security features to look for include:

  • Major investments in security technologies
  • 24/7/365 system monitoring
  • Immediate security support in the event of an attack

Also, remember that no Internet-connected system is 100% secure. Businesses should choose service providers that offer prompt and effective solutions for cyberattacks.


Best-in-class service providers take a proactive approach to maintaining high quality of service (QoS) levels. They will automatically monitor factors like data bursts, packet loss, system latency and jitter, among others.

Compatibility with Legacy Technologies

Mix-and-match approaches to providing equipment can create compatibility issues. Look for consistency, and work with a provider that offers a range of recommendations for supplementary infrastructure such as bandwidth, connectivity, system customization, handsets and headsets, and optional features.
